Oh boy, perhaps it wasn't that bad that Germany shut down its nuclear power plants:
On a UK nuclear submarine, bolts on the reactor chamber were 'repaired' with superglue, after some idiot (probably apefirmative-action, female-quota, trans-quota...) overtightened!? them. The faulty repairs were found after one of the bolt heads fell off during an inspection. I'd really like to see the face of the inspector when he discovered that!

The Royal Navy has ordered an urgent investigation amid claims that workers on a Trident nuclear armed submarine fixed broken bolts in the vessel’s reactor chamber using glue.
The faulty repairs on the cooling pipes aboard HMS Vanguard were found after one of the bolts fell off during an inspection, the Sun reported.
